Description

Technical Field

[0001] This utility model relates to the field of carbon monoxide concentration detection technology, specifically a carbon monoxide detection device in flue gas. Background Technology

[0002] When combustion and reaction are incomplete in a rotary kiln, carbon monoxide will be produced and mixed in with the flue gas. It has been found that the concentration of carbon monoxide affects nitrogen oxides, so it is necessary to detect carbon monoxide in the flue gas.

[0003] During the testing of flue gas, it is necessary to filter these impurities, as the flue gas contains solid particles such as coke and dust. The existing methods use filter screens or filter cartridges to filter these impurities. Cleaning filter screens or filter cartridges is often time-consuming and labor-intensive, resulting in frequent maintenance and high maintenance costs.

[0004] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0009] Preferably, the U-shaped tube is provided with a filter sleeve, the two ends of which extend from the two ends of the U-shaped tube. The thickness of the filter sleeve is uneven, with the thickness on the side in contact with the small hole being greater than the thickness on the other side.

[0010] Preferably, the inner walls of the two ends of the thinner side of the filter sleeve are provided with connecting strips (7), which extend from both ends of the filter sleeve.

[0011] Preferably, a metal wire is embedded in the thinner side of the filter sleeve, and a metal wire is also embedded in the connecting strip. The metal wire in the connecting strip is connected to the metal wire in the filter sleeve.

[0013] (III) Beneficial Effects

[0014] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides a carbon monoxide detection mechanism in flue gas. Flue gas is collected through a U-shaped tube and sent into an analyzer. The filter sleeve inside the U-shaped tube is a consumable. When the total amount of flue gas collected reaches the set value, it is only necessary to disassemble the connecting tube and the sealing tube by thread, tie the connecting strip on the new filter sleeve to the connecting strip on the old filter sleeve, and pull the old filter sleeve from the other end of the U-shaped tube to quickly disassemble the old filter sleeve and complete the new installation at the same time, which is convenient and quick.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] This utility model provides a carbon monoxide detection device in flue gas, such as... Figure 1-2 As shown, it includes a smoke outlet pipe 1, and a U-shaped pipe 2 is provided on the lower side of the smoke outlet pipe 1. The U-shaped pipe 2 passes through the smoke outlet pipe 1. Several evenly distributed small holes 3 are opened on one side of the curved part of the U-shaped pipe 2. The small holes 3 face the direction of the smoke flow in the smoke outlet pipe 1. One end of the U-shaped pipe 2 is threaded with a sealing sleeve 4, and the other end is threaded with a connecting pipe 5. The connecting pipe 5 is connected to the analyzer.

[0020] The U-shaped tube 2 is equipped with a filter sleeve 6. The outer wall of the filter sleeve 6 is in close contact with the inner wall of the U-shaped tube 2. The two ends of the filter sleeve 6 extend from the two ends of the U-shaped tube 2. The thickness of the filter sleeve 6 is uneven. The thickness on the side in contact with the small hole 3 is greater than the thickness on the other side. The thicker part completes the filtration of solid particulate impurities in the flue gas. The thicker part makes the filtration effect better.

[0021] Reference Appendix Figure 1-2The inner walls of both ends of the thinner side of the filter sleeve 6 are provided with connecting strips 7. The connecting strips extend from both ends of the filter sleeve 6. A metal wire is embedded in the thinner side of the filter sleeve 6, and a metal wire is also embedded in the connecting strip 7. The metal wire in the connecting strip 7 is connected to the metal wire in the filter sleeve 6. The metal wire increases the tensile strength of the thinner part of the filter sleeve 6 and the connecting strip 7. Since the outer wall of the filter sleeve 6 and the inner wall of the U-shaped tube 2 are in close contact, and since the outer diameter of the filter sleeve 6 is slightly larger than the inner diameter of the U-shaped tube 2, a large force is required when pulling the old filter sleeve 6. The steel wire inside ensures that the filter sleeve 6 will not break.

[0022] Flue gas is collected through U-tube 2 and sent into the analyzer. The filter sleeve 6 inside U-tube 2 is a consumable. When the total amount of flue gas collected reaches the set value, simply unscrew the connecting pipe 5 and the sealing pipe 4, tie the connecting strip 7 on the new filter sleeve 6 to the connecting strip 7 on the old filter sleeve 6, and pull the old filter sleeve 6 from the other end of U-tube 2. This allows for quick and easy removal of the old filter sleeve 6 while simultaneously installing the new one.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
